<p><P>PROBLEM TO BE SOLVED: To provide a three-phase electrical component capable of measuring accurately a current flowing in each three-phase AC power supply line. <P>SOLUTION: A bus bar assembly 12 and a sensor substrate 13 are assembled with a screw 25 in the arranged state in due order on a base part 11. In the bus bar assembly 12, three bus bars 14a, 14b are resin-molded so as to be positioned on the same virtual plane at prescribed intervals, and a plurality of metal sleeves 16a, 16b are resin-molded in the orthogonal state to the virtual plane. On the sensor substrate 13, three current sensors 24a-24c are mounted on prescribed positions corresponding to arrangement of the three bus bars 14a, 14b. The upper end of the metal sleeve 16a is projected from the surface of the bus bar assembly 12, and a recessed part capable of positioning the sensor substrate 13 to the bus bar assembly 12 by being fitted with the end of the metal sleeve 16a is formed on the sensor substrate 13. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
